This report contains a compilation of available textural data and lithologic descriptions generated on surficial sediment samples from off the northeastern coast of the United States. Over 49,000 samples containing sediment grain size and lithology have been compiled as part of the U.S. Geological Survey's National Benthic Habitats and Marine Aggregate Resources and Processes Projects. These data will be used to update the existent maps on surficial sediment distribution available for the Gulf of Maine and Georges Bank regions.
Many of these data layers were compiled from gray literature or unpublished sources and have not been available in digital form prior to this publication. These data have been converted to Environmental Systems Research Institute, Inc. (ESRI) "shapefile" format for use in the project Geographic Information System (GIS). Data are also supplied with complete FGDC compliant metadata. Sediment data and sample identifiers are also supplied in flat-file format and Microsoft Excel spreadsheet files for those users who may not have GIS access.
